Answer 1

You can do this using PIVOT (documentation)
SELECT P.[Name], P.A AS DeviceTypeA, P.B AS DeviceTypeB, P.C AS DeviceTypeC
FROM
(
SELECT U.[Name], D.DeviceName, D.DeviceType
FROM [User] U
INNER JOIN DeviceUser DU
ON DU.UserID = U.UserID
INNER JOIN Device D
ON D.DeviceID = DU.DeviceID
) AS X
PIVOT
(
MAX(X.DeviceName)
FOR X.DeviceType IN([A], [B], [C])
) AS P;
Note however that this will return only one device name for a certain user and device type even if there are more devices of a device type for a that user.
